Identifies a backing bean property (of type UIComponent or appropriate subclass) to bind to this component instance. This value must be an EL expression.

converter

javax.faces.convert.Converter

Yes

The value can either be a static value (ID) or an EL expression. When a static id is
specified, an instance of the converter type registered with that id is used. When this is an
EL expression, the result of evaluating the expression must be an object that implements the
Converter interface.

disabledOnClientSide

boolean

Yes

If true the input is rendered disabled on the client side and
a hidden input is used to actualy submit his value back to
the server.

displayValueOnly

but no input widget. Default is false.

displayValueOnlyStyle

normally. If not, no hyperlink is rendered but all nested
tags (=body) are rendered.

forceId

boolean

No

If true, this component will force the use of the specified id when rendering.

forceIdIndex

boolean

No

If false, this component will not append a '[n]' suffix
(where 'n' is the row index) to components that are
contained within a "list." This value will be true by
default and the value will be ignored if the value of
forceId is false (or not specified.)

helpText

String

Yes

id

String

Yes

An identifier for this particular component instance within
a component view.

NamingContainer (eg h:form or f:subview). The id is
not necessarily unique across all components in the current view

This value must be a static value, ie not change over the lifetime
of a component. It cannot be defined via an EL expression; only
a string is permitted.

immediate

boolean

Yes

A boolean value that identifies the phase during which value change
events should fire. During normal event processing, value change
events are fired during the "process validations" phase of request
processing. If this attribute is set to "true", these methods are
fired instead at the end of the "apply request values" phase.

validator

Only EL

A method binding EL expression, accepting FacesContext, UIComponent,
and Object parameters, and returning void, that validates the
component's local value.

value

Object

Yes

The initial value of this component. This value is generally set as a value-binding in the
form #{myBean.myProperty}, where myProperty can be any data-type of Java (also user-defined
data-types), if a converter for this data-type exists.
Special cases:
1) f:selectItems - value needs to bind to a list (or an array) of
javax.faces.model.SelectItem-instances
2) components implementing UISelectMany (e.g. h:selectManyCheckbox) - value needs to bind to
a list (or an array) of values, where the values need to be of the same data-type as the
choices of the associated f:selectItems-component
3) components implementing UIData (e.g. h:dataTable) - value needs to bind to a list (or an
array) of values, which will be iterated over when the data-table is processed

valueChangeListener

and returning void. The specified method is invoked if this component
is modified. The phase that this handler is fired in can be controlled
via the immediate attribute.

visibleOnUserRole

String

Yes

If user is in given role, this component will be rendered
normally. If not, nothing is rendered and the body of this
tag will be skipped.
